Apache
ant. This is the build tool described here. Tested with
version 1.7.0 and a single extension (see below)

The ant FTP task
requires an extension. This is Apache Commons
Net extension, version 1.4.1
is available for download. I extracted the file
commons-net-1.4.1.jar from the zip file and
moved it to the ant/lib directory, from which ant seems to access it
quite happily.

Apache Commons Resolver,
version 1.3.0. Download the zip file and extract
resolver.jar and put it somewhere where you can
find it again!
